Introduction

Overview

QR code payments let consumers pay at a Nayax-enabled machine using a payment app on their smartphone. Nayax supports two types of QR codes: Static and Dynamic, which differ in where the QR is placed, what information it contains, and when the consumer scans it during the vend cycle.

ℹ️
Note: Both QR code types require a Nayax-compatible device and a supported consumer payment app. Contact your Nayax account manager to confirm which QR payment method is enabled on your machines.
Term

Static QR Code

 
Static QR Code

A Static QR code is a fixed QR code placed directly on the machine, typically as a printed sticker. The code does not change between transactions.

What it contains: Only the machine ID. No product or price information is encoded.

How it works

  1. The consumer scans the Static QR code on the machine using their payment app.
  2. The machine is activated remotely via the Nayax platform.
  3. The consumer selects a product on the machine.
  4. The payment app approves the transaction.
  5. The product is dispensed.
💡
Tip: Because the QR sticker is fixed, it can be replaced if damaged without any configuration changes; the machine ID it references stays the same.
Term

Dynamic QR Code

 
Dynamic QR Code

A Dynamic QR code is generated by the Nayax unit in real time and displayed on the unit's screen. A new QR code is created for each transaction.

What it contains: The machine ID and information about the selected product, including price. The code is unique to each purchase.

How it works

  1. The consumer selects a product on the machine.
  2. The Nayax unit generates a QR code on the unit's display.
  3. The consumer scans the QR code using their payment app.
  4. The payment app approves the transaction.
  5. The product is dispensed to the consumer.
ℹ️
Note: The Dynamic QR code expires after the transaction is complete or times out. A fresh code is generated for each new purchase, so each QR code can only be scanned once.
